4 Types of Exercise in Later Life: How to maintain strength, balance, & independence in aging

It’s one of those cliches that is true: exercise really is very good for your health.

In fact, one expert in applied longevity wrote that:

“Exercise is by far the most potent longevity ‘drug’. No other intervention does nearly as much to prolong our life span and preserve our cognitive and physical function.” — Peter Attia, MD, in his book “Outlive.” (Note: the emphasis there is mine.)

If you’re an older adult: are you exercising regularly? And if so, are you doing enough of the “right” kinds of exercises?

People are often quite interested in “balance exercises for seniors,” especially if they’ve become concerned about preventing falls. Those are great, but there’s really much more to know and do, when it comes to exercise and aging.

Since exercise is such an essential activity that most older adults are under-using, in this article, I’ll explain what’s most important to know about exercising in later life, including what types of exercise to do.

Specifically, I’ll cover:

The benefits of exercising in aging
What to know about walking for exercise
Four types of exercise to make sure you do
Why balance exercises and strength are key to mobility and preventing falls
Protein intake and strength-building
The risks of exercise in aging and what to ask your doctors

Flu Shots for Older Adults: What to Know & Do for 2025

by Leslie Kernisan, MD MPH

It’s that time of the year: fall, which I think of as flu vaccination time.

I always think getting a flu vaccine is a good idea for most older adults. So I agree with the Centers for Disease Control (CDC), which is urging that people get vaccinated against influenza early in the fall (before the end of October 2025).

Now, vaccination against seasonal influenza can seem like a bit of a tricky topic. Many older adults are skeptical of the need to get a yearly vaccination against influenza. They aren’t sure it will help. Or they think that the vaccination will actually give them a mild case of the flu. Or they just don’t like needles.

Or maybe they aren’t sure which type of seasonal flu shot to get: the regular one or one of the newer “stronger” versions, designed for older adults?

And now that we have COVID-19 to contend with, vaccination for seasonal influenza might feel even more confusing for people.

Don’t let yourself be confused. In this article, I will share with you what I know about influenza vaccination and what I’ve learned about influenza in COVID times. I also have updates on the stronger flu vaccines that are now recommended for older adults.

This year, I agree with the CDC that it’s important for people to get their seasonal flu shot, and if you are an older adult, I recommend getting one of the three flu vaccines specifically recommended for older adults. (See below for more on these!)

Note: If you are age 65 or older and it’s been more than 2 months since your last COVID booster, you may be able to get your COVID fall booster shot at the same time.

In “normal” pre-COVID times, the Centers for Disease Control (CDC) estimates that every year, influenza affects 9-45 million Americans, causes 140,000-810,100 hospitalizations, and results in 12,000-61,000 deaths. In most years, influenza vaccination does help reduce hospitalizations and deaths (I go into details below).

So this year, it’s important to do what you can to reduce respiratory illness, to protect yourself, and to protect others. And getting vaccinated against influenza is one of the things we can do.

In fact, I’m about to go get mine. As a healthy woman in her 40s, I’m not that concerned about getting dangerously ill from influenza. Instead, I get my annual flu shot because I want to minimize my chance of getting sick and perhaps exposing my older patients to influenza.

Here’s what I’ll cover in this article:

The basics of influenza and vaccination against the flu
What we know about influenza and COVID-19
What to know about flu shots for older adults & the CDC’s new recommendations specifically for older adults
What’s new and resources for the 2025-2026 flu season
Which influenza vaccination is probably best for most older adults
What to do if your older parent or relative is unwilling or unable to get vaccinated
Whether it’s more important to get a flu shot or a COVID vaccination (or a booster)

Why Older People Fall & How to Reduce Fall Risk

by Leslie Kernisan, MD MPH

Why do aging adults fall? To be honest, people don’t usually ask me this.

Instead, they want to know things like “How do I keep my mother from falling?” or “What should I do? I fell recently and am worried it could happen again.”

After all, falls are a scary thing. Most people know that falls are dangerous for older adults.

The Center for Disease Control (CDC) reports that one in five falls causes a serious injury, such as a broken bone or head injury. Fear of falling can also seriously affect an aging adult’s quality of life and, sadly, can keep a person from being active and thriving.

So, many older adults and family caregivers are interested in fall prevention because the risks are so great. (According to Google, “balance exercises for seniors” is a popular search query; I do like balance exercises in aging, especially when combined with strength training and other exercises.)

And the good news is that although it’s not possible to prevent all falls, it almost always IS possible to take actions that will reduce the chance of a bad fall.

And it’s easier to take action once we understand more about why an older person has fallen.

If you want to learn more, you’re in the right place. In this article, I’ll cover:

How understanding why aging adults fall can help you keep an older parent — or yourself — safer,
Why personalized fall prevention plans work better than relying on general fall prevention tips,
The four-step process I use to help older adults prevent falls,
A practical example showing you how to use these steps to avoid falls yourself.

First, understand why older people fall

There are many reasons that aging adults fall. Most older people will be falling due to their own unique combination of reasons.

So how, exactly, should YOU go about reducing fall risk?

Now, you can — and should — try to implement the general tips that are often listed in most fall prevention resources: exercise, medication review with the doctor, vision checks, and home safety reviews.

But if you really want to help an older person avoid falls, I recommend you learn to better understand why he or she, in particular, might fall.

Why? Because when you understand the specific reasons an older person may be falling, you’ll then be able to:

Identify which fall prevention strategies are most likely to help the person you worry about,
Recognize risky situations, and take steps to avoid them,
Know which medical conditions — and which medications — to ask your doctors to look into,
Understand what may have caused a specific fall, which can help you avoid future falls.

In other words, learning why older people fall means that you’ll be able to figure out why an older person is likely to fall — and take steps to help them.

6 Steps to Better High Blood Pressure Treatment for Older Adults

by Leslie Kernisan, MD MPH

Have you been concerned about high blood pressure (hypertension)? Or are you worried about an older relative having a stroke or heart attacks?

You’re not alone. After all, hypertension is the most common chronic condition among older adults, and medications for blood pressure (BP) are among the most commonly taken drugs in the US.

Even more important: poorly controlled hypertension is a major contributor to the most common causes of death and disability in older adults: strokes, heart attacks, and heart failure.

So it’s certainly sensible for older adults – and for those helping aging parents – to think about lowering blood pressure.

And once you start thinking about high blood pressure, you’ll probably start to wonder.

Are the blood pressure medications you’re taking enough? Is your blood pressure at the “right” level or should you and your doctors work on changing things?

And what about that major research – the SPRINT trial — that made the news in 2015? (In this study, older adults randomized to aim for a lower BP did better than those who got “standard” BP treatment.)

These are excellent questions to ask, so I’d like to help you answer them.

Now, I can’t provide exact answers on the Internet. But what I can do is provide a sensible process that will help you successfully address these questions about lowering blood pressure.

In this article, I’ll share with you the process that I use to:

Assess an older person’s blood pressure management plan, and
Determine whether we should attempt changes.

If you’re an older adult, you can use this approach to get started assessing your own BP management plan. This will help you to better work with your doctors on assessing and managing your blood pressure.

If you are helping an older relative manage health, you can follow these steps on behalf of your relative.

UTIs and Urine Bacteria in Aging:
How to get the right diagnosis & when to take antibiotics

by Leslie Kernisan, MD MPH

Q: An older friend, who is in her 90s, has been having bacteria in her urine, but no symptoms. Despite treatment with antibiotics, she was still having bacteria in the urine, so the doctor recommended chronic antibiotics and a referral to urology.

What can be done when an elderly woman has bacteria in her urine but no symptoms? Can a urology consultation help?

A: This is a great question. People often think that your friend is having a “recurring urinary tract infection (UTI)” or even a chronic UTI. But actually, you are describing something called asymptomatic bacteriuria, which means having urine bacteria without symptoms.

Every older person and family caregiver should know about asymptomatic bacteriuria. Here’s why:

It’s very common in older adults. This condition is found in an estimated 20% of women aged 80 or older, and also affects older men. The older the person, the more common it is. Asymptomatic bacteriuria is even more common in nursing homes, where it’s estimated to affect 30-50% of residents.

It’s often confused with a urinary tract infection (UTI). This can lead to unnecessary — and potentially harmful — treatment with antibiotics.

It usually does NOT need to be treated with antibiotics. As I’ll explain below, research shows that people don’t live better or longer when asymptomatic bacteriuria is treated. In fact, such treatment can be harmful: one study found that treatment increased the risk of future (real) UTIs, and increased the risk of infection with antibiotic-resistant bacteria.

How to Avoid Problems Due to Aging Incapacity: The (Better) Durable General Power of Attorney

by Leslie Kernisan, MD MPH

One of the most common concerns I hear from people is “My older parent’s behavior is concerning me and I’m worried about her mental abilities.”

As I explained in a related article: it’s not always dementia but often it is. And unless an older person has done a good job planning ahead, it can be very hard and messy for others to intervene as needed.

But hopefully, that’s not yet your situation.

In which case, you might be wondering: Given that it’s so common for aging adults to eventually start slipping mentally — or to be suddenly disabled due to an accident or serious health crisis — what kind of planning should older adults and families do to avoid this kind of situation?

I’ve done some research on this question, and here’s what I found out.

One of the simplest — and often less expensive — smart planning approaches is for an older adult to complete a general durable power of attorney (POA) document.

Especially if the powers granted are broad — which they often are — a POA can enable the designated person (known as the “agent”) to step in and assist with finances, housing, safety, and anything else covered by the POA .

A durable POA allows an agent to take action once the older person is “incapacitated.” In California, such POAs can be used to move a person with dementia to a different living arrangement.

Now, the durable power of attorney approach isn’t perfect. Over the years, I’ve noticed that two broad categories of problems come up:

Concerns as to whether the agent might be using the POA to financially exploit the situation
Issues related to determining incapacity and whether the older person should be overridden.

In truth, I have occasionally encountered situations in which different doctors had different opinions on whether an older person was incapacitated. This troubles me, because agents should really only be stepping in and overriding older adults if we’re all sure they’ve lost capacity and are making decisions that don’t serve their overall goals, or are hazardous to others.

Still, a general durable POA is an excellent approach to consider. But I would recommend you pay special attention to how the document is drafted, in order to reduce the risk of financial exploitation and to avoid pitfalls related to determining incapacity.

In this post, I will share:

What I’ve learned about general durable power of attorney documents
Why determining incapacitation is often problematic in the real world
Tips on avoiding a common POA weakness
What to know about including third-party accounting and other strategies recommended by the American Bar Association, to reduce the risk of financial exploitation by an agent

Q&A: How to Diagnose & Treat Mild Cognitive Impairment?

by Leslie Kernisan, MD MPH

Q: I realize that I sometimes have difficulty connecting a name and a face. I presume that this is mild cognitive impairment.

On researching the topic online, I find a variety of suggestions for alleviating it. These include supplements (lipoic acid, vitamin E, omega 3s, curcumin), food choices (fish, vegetables, black and green teas), aerobic exercise, yoga, and meditation.

Do these actually help with mild cognitive impairment? What’s been proven to work?

A: It’s common for older adults to feel they’re having trouble with certain memory or thinking tasks as they get older.

I can’t say whether it’s mild cognitive impairment (MCI) in your particular case. But we can review what is known about stopping or slowing cognitive changes in people diagnosed with MCI.

First, let’s start by reviewing what MCI is, and how it’s diagnosed. Then I’ll share some information on the approaches you are asking about, as well as other approaches for treating MCI.

How to Use a Personal Health Record to Improve Healthcare in Aging

by Leslie Kernisan, MD MPH

Everyone wants to get the right medical care. But doctors are often lacking key medical information at the time they see you (or, your aging relative).

The solution: setting up and using a personal health record (PHR).

This is a big step up from what many people do, which is to create an “in-case-of-emergency” packet. Such medical information packets usually include a list of medications, chronic conditions, and allergies, along with the names of next-of-kin and perhaps a POLST form.

I’ve reviewed such medical information packets, and they are certainly better than nothing. But in general, they don’t help older adults avoid these very common — and potentially serious — problems with their medical care:

Delays in treatment/action because test results aren’t available. Often doctors need test results in order to know how to proceed medically. If tests have been done but the results aren’t available, the doctor’s options are to fly blind, re-order the tests, or plan to request the test results and then see you again once the results are available.
Getting worse care in the emergency room, or in urgent care. An urgent medical problem often means seeing new doctors. Those doctors have to offer help quickly, but if they are lacking detailed medical information, it’s generally harder for them to offer the right medical management.
Suboptimal medication prescribing. Whenever medications are prescribed without first considering all other medications being taken, an older adult’s health is being put at risk. Although bringing an up-to-date medication list (or better yet, all the medication bottles) is very helpful, it’s also valuable for doctors to understand why another doctor prescribed a medication.
Suboptimal care from a new primary care provider (PCP). Adults in late life often move and have to establish care with a new PCP. Especially when an older person has multiple chronic conditions or a complicated health history, delays in getting medical information means it often takes the new PCP months to get up to speed so that he or she can properly help the older person with his or health concerns.
Inadequate help from a specialist or consultant. Aging adults are often referred to specialists, but studies have found that specialists often don’t receive enough information to do their work. Again, at best this means delays and inconvenience for you; at worst this can lead to serious health problems if you get the wrong care, or get the needed care too late.

Fortunately, even a very basic and low-tech PHR can help you avoid the problems listed above, and will improve your personal health information management.

At a minimum, you’ll save yourself hassle and the extra appointments that get scheduled because the doctor didn’t have the needed medical information the first time around. You’ll also spare yourself the discomfort and expense of enduring duplicate testing.

More importantly, properly maintaining and using a personal health record (PHR) will go a long way to ensuring that you get better, safer medical care. It can also help you avoid potentially life-threatening medical mishaps.

The key is to learn what medical information to put into this PHR, and how to use it effectively for care coordination. This post will tell you what you need to know, to set up and use a PHR.

10 Useful Types of Medical Information to Bring to a New Doctor

by Leslie Kernisan, MD MPH

Personal health information to bring to a new doctor

Here’s a situation that comes up for many people: you move in later life.

Or maybe it’s your older mother — or father, or other older relative — who’s moving to a new town, perhaps to be closer to you, or otherwise be somewhere more conducive to aging in place.

Such a move means that you’ll need to establish care with a new primary care provider.

For most older adults, establishing a good working relationship with a new health provider is a challenge. If nothing else, it can take some time to feel that each party knows and understands the other.

But it’s also in many cases a terrific opportunity to review a person’s health and healthcare. Provided, of course, that everyone involved makes an effort, and has good information to work with.

In this post, I’ll share my list of the most useful medical records and health information that you should bring to that first visit with the new primary care provider.

Do you have to bring this information? Of course not. In my own experience, most people bring nothing more than a medication list, if that. And they leave it to the new doctors to request health information from the previous doctors, which often arrives well after that first new patient visit.

But this is a problem, because it makes it quite difficult for that first visit to be truly useful.

Sure, the doctor can interview you, and do a physical exam. Yet for many older adults, that interview and exam is often much more productive if a doctor can combine it with a review of the most useful health information.

I myself used to see a fair number of new older patients, when I was a primary care geriatrician at the Over 60 Health Center. Those first visits often felt like fumbling around in a dark room, feeling the walls and furniture and trying to get a sense of the overall layout.

But occasionally, a new patient would come with useful health information in hand. This generally made a big difference in how quickly we could ensure that our new patient was getting the right medical care from us, and from other involved doctors.

So if you want to have the best start possible with a new doctor — or help your aging parent do so — you’ll need to do a little advance preparation. This often requires some time and energy. But it will pay off, by ensuring that the new doctor has the information he or she needs, to provide you with good healthcare.

Also, if you are in that season of life where you’re starting to be more involved with your aging parent’s health (or think perhaps you should be), this is a great opportunity to learn more about your parent’s health.

10 Useful Types of Medical Information to Bring to a New Primary Care Provider

Here’s my list of what I ask patients and families to bring to me, in order to make that new patient visit most useful.
